LUA Item Error when Guide Loads

[pyrowolf]

Just coming back to WoW after a long break, updated everything and of course there would be issue. So I made a backup of my addon's folder. Re-installed Zygors and a few other addon's and tried again. Still errors. So I disabled EVERYTHING but Zygor's and I am stilled getting the LUA error below. It was happening only when making a gear suggestion / auto equip. Now it's every time it loads. I did do some limited searching so if this is resolved in another post, please accept my apology. But I was unable to find anything dealing with this.

Thank you as always for an amazing product.

Try resetting the guides by going to your WoW/WTF/Account/<accountname>/SavedVariables folder and delete the Zygor files in there.
